Vietnam to Cambodia Overland: Crossing from the Mekong Delta by Bus or Boat

Going from Vietnam to Cambodia without flying is one of the most rewarding ways to link the two countries. The land is flat, green and busy with water, and the border sits in the middle of the Mekong Delta, the same river system you will have been looking at for days. This page covers the route from the south of Vietnam only. Hanoi is far from Cambodia, and a traveller starting in the north normally reaches the south first, which is a long domestic leg described elsewhere.

The overland route in one picture

Everything on this route runs through the south of the country. The usual line is Ho Chi Minh City, then the Mekong Delta (often with a night in Can Tho or Chau Doc), then the Cambodian border, then Phnom Penh and, further on, Siem Reap and the temples of Angkor.

There are three practical ways to cross:

Route	Starting point	Mode	Character
Direct road route	Ho Chi Minh City	Bus	Simplest, most frequent, least scenic
Mekong river route	Chau Doc	Boat, sometimes with a road section	Most scenic, more steps
Coastal route	Ha Tien, or Phu Quoc by ferry	Bus or minibus	Leads to Kep, Kampot and the Cambodian coast

None of these is a day trip in the sense that people use it for Hanoi’s surroundings. Count on most of a day between the cities, more if you continue to Siem Reap. Any number you read, including ours, is an order of magnitude: border queues, river levels and bus schedules all move it.

If you are still choosing between the south and the rest of the country, the Vietnam and Cambodia in three weeks itinerary shows how a full trip fits together, and how to enter and leave Vietnam by land puts the crossings side by side.

Start with the visa, not the bus

Before you book any ticket, settle the paperwork. Entry rules depend on your nationality and they change, so no travel site, including this one, should be your final authority.

• Vietnam: check the official immigration portal and your own government’s travel advice. Vietnam issues an e-visa valid for up to 90 days to a broad list of nationalities and gives short visa exemptions to some countries. Whatever you hold, it must cover both your exit and, if you plan to come back, your re-entry.
• Cambodia: it has its own official visa system. Check the Cambodian government portal and your own government’s advice, not a bus company’s assurances.
• Land borders and e-visas: some visas are valid only through named entry and exit points. Confirm on the official portal that the land crossing you plan to use is accepted for your visa type.

The rest of this section matters because the number one mistake on this route is leaving Vietnam on a single-entry visa and then wanting to return. If your plan is Ho Chi Minh City, then Phnom Penh, then back to Ho Chi Minh City for a flight home, you need a visa that allows a second entry, or an exemption that allows it. A single-entry visa is finished as soon as you walk out through the Vietnamese border post.

Our Vietnam visa guide explains the general options, and the visa tool points you to the right official page. Neither replaces the official portal.

The same logic applies in reverse. If you travel the other way, from Cambodia into Vietnam, the Vietnamese visa must be in place before you reach the border post in most cases, and it must start on the date you cross.

Route 1: Ho Chi Minh City to Phnom Penh by bus

The direct bus is the default choice, and for most people it is the right one. Buses leave from the main areas of Ho Chi Minh City and run north-west across flat country towards the border, then continue to the Cambodian capital.

What to expect:

1. Pick-up. You are usually collected or told to arrive at an office in the backpacker area. Confirm the exact departure point the day before, because several operators use different spots.
2. Border formalities. The bus stops at the Vietnamese side, where passengers get off with their luggage, queue at the exit counter and have their passports stamped. You then walk to the Cambodian side and repeat the process. The bus is waiting on the far side.
3. Cambodian entry. If you need a visa on arrival, the official fee is posted at the counter. Anything much above it is a request for an unofficial payment.
4. Continuing to Phnom Penh. After the border the road runs through rural Cambodia and across the Mekong towards the capital.

Bus operators sell tickets that include the border. That is convenient, but it also means you are trusting the operator with your passport at one point in the day. Keep it on you where you can, and do not hand it to a tout. An operator who insists on collecting passports for a fee that is not on the ticket is a reason to walk away.

For the general logic of long-distance buses in Vietnam, including sleeper services on other corridors, see the sleeper bus guide. The border run is a different animal, usually a seated coach by day.

Route 2: the Mekong by boat from Chau Doc

The river route is the one travellers remember. Chau Doc lies on the Bassac river near the Cambodian frontier, and from there the boat follows the river system into Cambodia, past floating villages and fish farms, to Phnom Penh.

This route works especially well if you are already travelling through the delta. A common sequence is:

• Ho Chi Minh City by road into the delta, with a night in Can Tho.
• A visit to the Cai Rang floating market at dawn, since the market trades early in the morning and is gone by mid-morning.
• Onward to Chau Doc by road or river, then the boat to Cambodia the next day.

On the boat route the border is crossed by water. Vietnamese exit formalities happen at a post on the river, then you reach the Cambodian post, where visas are checked or issued, before the journey continues by boat or by road.

Things to know before booking:

• Water levels change the service. During the dry season the river is lower and some operators change the vessel, the route, or add a road section. Ask exactly what you are buying: boat only, boat plus bus, or bus only.
• Operators vary. Some sell the whole journey as one ticket from Chau Doc, others sell a day transfer only to the border. Compare what is included.
• Do not buy the journey from a person who approaches you on the quay. Book through your accommodation or a reputable agency.

If you want to explore the delta properly before leaving, our guide to Mekong Delta tours from Ho Chi Minh City and the guide to boat trips in the delta cover the day-trip options. A multi-day itinerary such as a five-day southern Vietnam tour from Ho Chi Minh City can also be a way to cover the delta in one go before going on.

Route 3: the south-west coast via Ha Tien

There is a third possibility for travellers who want the Cambodian coast rather than the capital. Ha Tien sits on the south-western edge of Vietnam, close to the border. From there road transport continues towards Kep and Kampot, which are quieter than Phnom Penh and often chosen as a first stop.

This route also suits visitors who have come from Phu Quoc. The island has its own airport, and it is reached by sea from the mainland as well. Phu Quoc has its own entry scheme for direct arrivals, and that scheme does not replace the general rules: if you are using Phu Quoc as your base, check the official portal for what applies to your nationality and to leaving by land. Our Phu Quoc island guide covers the island itself.

Choosing between the routes

If you…	Choose
Are in Ho Chi Minh City and want the simplest option	Direct bus to Phnom Penh
Are already in the Mekong Delta	The Chau Doc boat or a road transfer
Want Kampot, Kep and the coast	Ha Tien crossing
Plan to return to Vietnam	Any route, with a multiple-entry visa or exemption

If you are short on time and the cities matter more than the ride, a flight between the two countries exists, but it is a different page’s job. This guide is for people who want to see the ground between. For general transport options across the country, start with getting around Vietnam.

Making the delta part of the trip

The delta is not just a corridor. If you have a day or two to spare, spend them well.

• A half-day or day on the water, such as a wildlife kayak and boat outing in the delta, shows the canals that the bus never sees.
• Cu Chi is on the north-west side of Ho Chi Minh City, roughly 60 to 70 kilometres out, so it fits the same direction of travel. A speedboat trip to the Cu Chi tunnels is one way to see it before you leave the city.
• Can Tho is the largest city in the delta and a natural overnight stop.

Remember that My Tho and Ben Tre are the closest delta towns to the city, about 70 kilometres away, while Can Tho is about 170 kilometres away and Chau Doc is the far end. Mui Ne and its dunes are on the coast to the north-east and are not part of the delta.

Money at the border

Money is where travellers lose the most at a land crossing. Some practical points:

• Spend or change your Vietnamese dong before you leave. It is hard to use in Cambodia.
• Cambodia uses its own riel, but US dollars are widely used for larger payments there. Carry small notes in good condition.
• Do not change money with people on the roadside at the border. Rates are poor and counterfeit notes exist.
• Keep a few small Vietnamese notes for water and snacks on the way to the border.

The money in Vietnam guide explains how cash and cards work on the Vietnamese side.

Scams and small frictions

Most land crossings go smoothly, but the border region is known for a few habits:

• Extra fees. Someone says your visa needs a stamp fee or a health check payment. Ask for the official sign, and ask the operator to show where the fee is posted.
• Passport collection. An operator collects every passport on the bus. This is common and usually harmless, but it should be your choice.
• Changed tickets. A direct ticket turns into two separate vehicles. Ask what is included before you pay.
• Hotel drop-offs. A driver takes you to a hotel that pays a commission. You are free to say no.

For a wider view, see scams to avoid in Vietnam and the note on travel insurance, since a missed onward connection is exactly the kind of thing a policy may or may not cover.

What to pack for the crossing day

Keep a short list on you rather than in the hold:

• Passport with sufficient validity and blank pages, and a printed copy of any e-visa.
• A few passport photos, in case the Cambodian side asks for one.
• Cash in small notes, both US dollars and some Vietnamese dong for the start of the day.
• Water and a snack. Tap water is not drinkable in either country.
• Your onward booking printed or offline on your phone.

When to travel

The delta is hot all year. In the south the dry season runs roughly from December to April, which is the easiest time for river travel and for long days on the road. The wet season, roughly May to November, usually brings short late-afternoon downpours rather than all-day rain, so mornings are the best time to cross. Avoid Tet, the lunar new year, between late January and mid-February: transport is fully booked, businesses close and prices rise, and the date changes every year.

Frequently asked questions about going overland from Vietnam to Cambodia

Which is the most common overland route from Vietnam to Cambodia?

The most common route runs from Ho Chi Minh City to Phnom Penh by direct bus, crossing the border on the road north-west of the city. A second popular route starts in the Mekong Delta at Chau Doc and continues by boat or road to Phnom Penh.

How long does it take to go overland from Vietnam to Cambodia?

Plan on most of a day between Ho Chi Minh City and Phnom Penh, including the border formalities, and more if you continue to Siem Reap. Treat any single published duration as an order of magnitude, because border queues vary.

Can I cross the border with a single-entry Vietnamese e-visa and come back later?

No. A single-entry visa is used up when you leave Vietnam. If you plan to return, for example to fly home from Ho Chi Minh City, you need a multiple-entry visa or an exemption that allows re-entry. Check the conditions on the official immigration portal.

Do I need a Cambodian visa before arriving?

That depends on your nationality and the type of visa. Cambodia has its own official e-visa system and its own rules. Check the Cambodian government’s official portal and your own government’s travel advice rather than relying on an agent or a bus company.

Is the boat from Chau Doc better than the bus?

The boat is more scenic and the border formalities are handled with a guide, but it depends on water levels and operators. The bus is simpler to book from Ho Chi Minh City. Neither is a clear winner; choose by where you start and how you like to travel.

Should I change money before crossing?

Carry a little cash in US dollars and a small amount of Cambodian riel, which is common in Cambodia, and spend your Vietnamese dong before you leave, since it is hard to use or change outside Vietnam. Do not accept inflated rates from touts at the border.

Is it safe to cross overland?

Yes for most travellers, and many people do it every day. The usual risks are overcharging, unofficial fees at the border and missed connections. Use a reputable operator, keep your passport and valuables on you, and ignore anyone who says your visa needs an extra payment.
